Why Advanced Aliens Probably Don’t Build Dyson Spheres

🫣🤫🤔 Let’s face it: we’re still a Type 0 civilization on the Kardashev Scale… though, to be honest, we’re much closer to the Kardashian Scale 😁 endless entertainment, constant distractions, and celebrity obsession. 🙈🙉🙊 A true Type I civilization would be focused on mastering energy, advancing science, and solving humanity’s biggest challenges. We’ve still got a long way to go! While most people’s main concerns revolve around material comfort, entertainment, and instant gratification, who truly cares about the fate of the most vulnerable? About social exclusion? Inequality? The pollution and destruction of our environment? Who cares about the massive extinction of million of species now underway? Who cares about sustainable development and peace for everyone? A true Type I civilization would be collectively focused on optimizing how it functions and shaping a better future for everyone. We’re still very, very far from that.

RNA-binding protein diversity and NLS arginines regulate FUS mixing in mRNA-rich compartments

Valenti et al. used the MT bench assay to quantify FUS homotypic/heterotypic interactions in compartments of heterogeneous compositions in cells. They showed that FUS heterotypic interactions with other RBPs, orchestrated by its disease-related NLS, prevent FUS phase separation independently from nuclear transporters.

Engineers create 3D-printed robotic fish that swim, play and recharge themselves through automated charging systems. Here’s all you need to know

Engineers have developed robotic fish that mimic real aquatic life, offering an aquarium experience without the upkeep. These miniature submarines, powered by Arduino and guided by an overhead camera and Raspberry Pi, autonomously navigate, interact, and even return to a wireless charging station. This innovation promises a maintenance-free aquatic display, blending technology with the tranquility of nature for a futuristic aquarium.

Does time come from the entire universe running computations?

Explaining the passage of time has been a gnarly problem in physics basically forever, but physicist and computer scientist Stephen Wolfram has a radical proposal for where it comes from. He discussed his ideas on time – and what they mean for free will – with reporter Leah Crane

Small transistor sharpens low-cost thermal cameras without extreme cooling

With help from a small transistor, a team of researchers led by Professor Fengnian Xia figured out a way to make a type of thermal imaging technology dramatically more accurate. The results are published in Nature Sensors.

Robots, drones, self-driving vehicles and other autonomous devices rely on thermal sensing and imaging to navigate the spaces they travel in. It’s also used in many other technologies, including night vision, remote thermometers and rescue operations.

George Dyson on Turing’s Cathedral: In Wildness Is The Preservation Of The World

Fourteen years ago, I sat down with George Dyson to talk about “Turing’s Cathedral.”

We talked about the machines that were coming. Now they are here.

Dyson watched the digital revolution get built from the inside. His father was Freeman Dyson. Einstein’s secretary was his babysitter. He grew up at the Institute for Advanced Study in Princeton, playing in the halls where Turing’s ideas became von Neumann’s machines.

He gave me a line I still cannot shake:

“There is no way to completely govern the digital universe. It will always be a wildness, not a bureaucracy or a national park.”

Read it again. Then look at every #AI governance debate happening right now.

Scientists unlock gut-healing power of fruits and nuts paired with the right gut microbes

University of Louisville researchers have discovered how a naturally occurring microbial compound may help protect the gut and support future treatment strategies for inflammatory bowel disease (IBD).

IBD, which includes conditions such as Crohn’s disease and ulcerative colitis, affects millions of people worldwide. The disease is characterized by chronic inflammation and damage to the intestinal lining. A healthy gut barrier helps keep harmful bacteria from leaking out of the intestines while allowing nutrients to enter the body. In people with IBD, that barrier becomes weakened, leading to inflammation, pain and long-term complications.

A research team led by Venkatakrishna Rao Jala, associate professor in the Department of Microbiology and Immunology and UofL’s Brown Cancer Center, discovered how a naturally occurring microbial metabolite called urolithin A, or UroA, which is generated by gut bacteria after digestion of foods such as pomegranates, walnuts and berries, activates a protective pathway in the intestine that may help preserve gut health.
